What you need

Step 1

              Power Cord

Keep in mind that there are two DIFFERENT kinds of screws on the base plate:
Three 3/8" standard Phillips screws…
And one 3/8" non-standard triangular Phillips screw.

Step 2

Remove the “K” rubber pad, then remove the three 3/8" Phillips screws from the baseplate using a #1 Phillips screwdriver.
Remove the non-standard Phillips screw.
Attempting to remove with a standard Phillips screwdriver will damage the screw head and potentially prevent its removal.

Step 6

Use your hands to pull the black cylinder out from the center of the baseplate. This is the power coupling.
Take note of the arrangement of the wires on the coupling device to aid in reassembly. If desired, mark the wires and connectors with different colored tapes.
The GREEN wire is the ‘ground’ or ‘protection’ wire. It is connected to the center post.
The other two wires are both BLACK. You can distinguish them by feel:
The smooth wire is the ’neutral’ wire.
The ribbed wire is the ‘hot’ wire.

Step 9

You will need three 16-22 gauge connectors (spaded lugs). The ‘gauge’ number refers to the wire size the lug connector is designed to fit. These connectors will slip over the contacts on the power coupling.

Step 10

On the replacement cord, remove the white, green, and black protective caps. By hand, affix one connector to each cord wire. Follows these steps for each wire:
Twist the copper strands on the wire so you can cleanly insert the wire into the connector.
Push the copper wiring into the connector until the insulation prevents further insertion.

Step 11

Using the multi-tool in crimper mode (or a special crimping tool), apply pressure on the connector ‘shank’ where the wire was inserted.
The ridge that you achieve by crimping should look the same as the connector shown here on the green wire. Give the connector a gentle pull to confirm it is well connected to the wire (it should not slip off).
Repeat steps 10 and 11 for the remaining two wires requiring connectors.

Step 12

Thread the replacement cord through the opening closest to the cord symbol on the bottom of the baseplate.
Insert the cord until the green, white, and black wires are pushed all the way through.

Step 13

Reinsert the power coupling (the black cylinder) through the baseplate.
Slide the connectors into the exposed metal prongs protruding from the power coupling. This may require a little force because the connection is a tight fit.
Reattach the black plastic oval piece in order to secure and stabilize the cord wires.

Step 16

Align the holes on the two halves of the baseplate precisely.
Using a #1 Phillips head screwdriver, tighten the three 3/8" Philips head screws in the holes located along the outer edge of the base plate.
Using a #1 TRIANGULAR head screwdriver, tighten the 3/8" TRIANGULAR Phillips screw at the center of the base plate.
